Abstract: PAN STACKING SYSTEM                  ABSTRACT OF THE DISCLOSURE         Articles which nest, such as baking pans, are assembled into a stack by a two-stage lift mechanism in which the assembly of a second stack is commenced while a previously assembled first stack is being discharged from the stack form-ing apparatus, so that the flow of pans into the apparatus need not be interrupted.  Articles such as pans are fed in succession into a stacking station at which the articles are aligned with a vertical path and then dropped. A first stage lift receives the articles and is lowered one step upon the receipt of each article until the first stage lift is lowered to a transfer station. At the transfer station, support of the stack of articles is transferred to a second stage lift which is similarly lowered one step upon the addition of each subsequent article to the stack until a preselected number of articles have been accumulated in the stack.  Upon transferring the support of the stack to the second stage lift, the first stage lift is retracted clear of the stack and returned to its upper limit of movement.  When the final article has been stacked on the second stage lift, the first stage lift is re-inserted into the vertical path to receive the next following article to commence assembly of a second stack.  Simultaneously the second stage lift is lowered to a discharge station where the stack is discharged from the second stage lift which is then elevated back to the transfer station.  The stacker is capable of stacking both bread and bun pans, which are of different height and capable of delivering pans to a discharge conveyor without stacking them.

Granted: 1981-12-29
Abstract: ABSTRACT OF THE DISCLOSURE        The invention provides an apparatus for transversely stretching and molecularly orientating a continuously advancing flexible web, comprising an arrangement for preventing substantial inward movement of the web margins and a pair of opposed hanks of transversely spaced pressure elements between which banks the web can travel whilst its margins are engaged by the restraining means.  The pressure elements of one bank are transversely staggered in relation to the elements of the other bank, and, as seen looking in the transverse direction, overlap the pressure elements of the other bank with such a degree of overlap that the pressure elements cause the web to take up an extended form from margin to margin by applying opposed forces respectively to the opposite surfaces of the web at spaced locations across the width of the web and transversely stretch the web into a pleated form without substantial inward movement of the web margins.  The pressure elements of at least one of the banks are stationary pressure members having web-engaging slide surfaces arranged to provide a gradually increasing amount of overlap with the pressure elements of the other bank in the direction of advance of the web.  A drive arrangement is provided for continuously advancing the web longitudinally between the banks so that the pressure elements continuously transversely stretch the web.  In this manner the angle of attack of the pressure elements on the web can be reduced to allow proper feed of the web, particularly in the centre.  In addition, the rate of transverse stretching can be more accurately controlled.

Abstract: ABSTRACT            Apparatus and method for honing internal sur-faces of a workpiece wherein at least one of the surfaces to be honed is a flat or non-circular aperture.  Movable honing stones are mounted in a holding tool such that they can move back and forth transversely of the honing tool as the honing tool is moved longitudinally of the surface to be honed.  A first series of honing stones is mounted in a series of parallel slots formed in the honing tool at an angle such that when the tool moves in a first longitudinal di-rection the honing stones will move to one side of the tool due to reaction forces and due to the angle at which the mounting slots are formed in the tool.  A second series of honing stones is mounted in a second plurality of parallel slots formed in the tool such that they move transversely in a direction opposite to the first plurality of stones when the tool is moved in a first longitudinal direction.          The result is that the first and second plurality of stones alternately move back and forth transversely with respect to the tool as the direction of travel of the tool changes resulting in a very precise and effective honing operation as well as providing that the tools are self-cleaning.  In a preferable arrangement the first and second plurality of stones are mounted in slots which are at an angle of 45° with the longitudinal axis of the tool.
